Brute Force


Siller Helicopters Inc. performs precision commercial heavy-lift jobs and aerial construction support across the USA flying two Sikorsky S-64 Skycranes, two CH-54 Tarhes, and two S-61s. Founded in 1975 and based in Yuba City, California, it is highly experienced in all aspects of this demanding and specialized work. The experience of its pilots-in-command mirrors the company, with an average of 10,000 flight hours, and Siller employs several aft seat pilots to guarantee precision on each job. Siller also is known for providing high quality and meticulously maintained firefighting aircraft on both contract and call when needed, with the help of its own full-service repair facility.


64 July/Aug 2019


Rotorcraft Pro observed a recent Siller lift job at a large mall in Roseville, California. The job entailed lifting eight 6,500-pound air conditioners, more than a Sikorsky S-58T can lift but well below the maximum 11,000 pounds its S-61 can handle. For jobs up to 10,000 pounds, nothing is better than a light S-61. It also hauled off a few loads of support scrap metal from the air conditioning base plates. Precision flying is typical for such jobs, so this one was not particularly challenging for the flight crew. The mall was near sea level and it was a cool morning, so the S-61 had plenty of excess performance. This gave the flight crew plenty of options to complete the job safely and efficiently.
